' Application inea october 11,1833. (No modal.)

To all whom it muy concern:

.'Be it known that I, MILTON H.l BlissETT, a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Devices for use in Putting Locks and Analogous Articles 4:in Place, of which the following is a specification. Io My invention relates to a device, which I term a lock-marker,77 for use in laying out the mortise, spindle-hole, key-hole, or other places to be bored or cut in attaching locks in their proper places. v I 5 My invention is applicable for usein attaching many articlesof builders hardware in place-as, for instance, locks and their escutcheons to' drawers and doors, and any other work in which it is required that certain cuttings or borings shall be definitely located with reference to the edge of the door, drawerfront, or other body to which said locks orother articles are to be applied.

The object of my invention is to furnish a 2 5 cheap .and simple device for laying out the work hereinbefore named, so that the work may be done more expeditiously, thereby effecting a large saving of labor, and also so that the work may be done more accurately, 3o whereby the cuttings and borings may bemade exactly the proper size and shape, and thereby produce a much neater job. I attain these objects by the simple construction and device illustrated in the accompanying drawings, in 3 5 whichn Figure l is a perspective lview of a portion of a door with my marker applied thereto in proper position for use for marking the depth or vertical width of the lock-mortise, and for 4o marking the location and form of the spindle hole and key-hole. Fig. 2 is a like view of the same portion of the same door with my marker applied in positionv for marking the -location and form of said -spindle-hole and key-hole upon the opposite side of the door. In this instance that portion of the marker which is hidden from view is indicated by broken lines. Said figure also represents the marks for the spindle-hole and keyhole as 5o having been laid out upon the door while the marker was in the position represented in Fig. 1. Fig. 3 represents a face View of my marker as adapted for a lock having two spindle-holes and two key-holes, as ordinarily employed in night latches or locks.

In all the Iiguresof the drawings, A designates a wing or blade, whose edges a (t are a -distance apart equal to the width or vertical the hinge or joint b by a series of perforations,

which extend in aline at right angles to the edges a a. The surface of the Wing or blade B has imprinted upon it marks or indices to designate the proper locations, size, and form of all thecuttings and borings which are to bc made upon the broad side of the door-stile, and also to indicate the positionsfor the centers of the borings. 'Ihe broken circle c indicates the location and size of the bore which receivps the ordinaryiknobspindle, and the dot in the center thereof indicates the location for the point of the boring-bit. The broken lines el indicate the proper location, size, Aand form for the key-hole, while the dot near the .upper portion thereof indicates the location for the point of the bit in boring the upper end of the key-hole.

`In Fig. 4 the distance between the edges 'a a indicate the width of the lock as in the other ligure; but as this marker is `for use with a rim-lock, there will be no mortise to bemade in the door. Y In said iigurethe broken circles and their center dots, e, indicate the location of 9o the screw-holes for-the reception of the screws in securing the lock to the side of the door.

In Fig. 5 the circlef audits center dot indicate the size, position, and center for the hole which receives the second latch or bolt-spindle, and the key-hole diagram f/ the size, form, 8mo., of the additional key-holes found in the ordinary `night latches or locks. Dots for marking the screw-holes for the keyhole escutcheons may also be added, if desired. Ifo

-Theseveral marks, lines, &c., in the various markers for the different articles may be made by printing in an ordinary printingpress, either upon paper or other iexible material when in sheets of the proper size, or they may be printed upon a larger sheet, as shown in Fig. 3, for use when in that form, or by first trimming the paper down to the lines a a. In 5 case these lines are formed by a series of perforations, this trimming can readily be done by tearing off the paper' on said lines.

If. desired, when my marker is printed on sheets larger than is necessary to form the 1o marker, as in Fig. 4f, the sheets maybe still larger, and large enough to serve as the usual wrapper for the locks in packing.

In order to use my marker I iirst fold or bend the marker carefully on the line b, and the reason for forming said line by a series of perforations or indentations is to make it fold accurate] y on said line. The marker is so bent until the wings or blades stand at right angles to each other, or thereabout, and then the 2o marker is placed upon the door, at the desired point for attaching the lock, with t-he blade B lying ilat against the broad side of the door, and with the blade A pressed flat against the edge of the door after the manner of a try- 2 5 square, as shownin Fig. l, thereby causing the blades A B to be properly gaged and squared in the position from the corner edge of the door, which, in this instance, is the working edge. The edges a a are then used as indices, 3o by which to lay out the upper and lower edges of the mortise on the edge of the door, as indicated by the marks lzy l1, Figs. l and 2, and then, by means of a suitable piercinginstrument, vthe paper is punctured through the center dot of the circle c, at the same time running the instrument through the paper far enough to print a corresponding center mark in the door; and, if desired, the general outlines of the circle may also be pricked 4c through upon the door, so that when the workman bores the spindle-hole he can ascertain whether or not his bit is following the center mark. In a like manner the center dot for boring and the contour of the key-hole may be pricked through upon the door. The marker is then removed, and the marks c d Vwill be seen upon the door, as shown in Fig. 2. rlhc marker is then refolded on the line b, so as to reverse the wing A, when the marker is again 5o placed upon the opposite side ofthe door and adjusted in position until the wing A is between the mortise-marks h lz, previously made upon the edge of the door, as shown in Fig. i. rFhe markings for the spindle-hole and keyhole may then be pricked in upon the opposite side of the door in the manner before described. The marks for the two opposite sides of the door will be exactly in line, and a neat job can be effected by boring and cutting from 6o both sides. Ordinarily, thc edge ofthe door will be beveled a little, and if the lock has a right-angular face-plate, the mortise should be made to slant a little to one side, to bring the face-plate parallel to the face of the edge ofthe door. In such cases the marker will properly lay out the work in the manner hereinbefore In some cases the face-plate is bevdescribed.

eled a little, and the edge of the door correspondingly beveled, and then the boring and cutting can be varied from the marks just the distance that the edgeis out of square, or, after properly squari ng the blade B and marking the position for its horizontal edges by a light pencil mark or marks, it can be slipped to one side just the proper distance before the holes for cutting and boring are marked, or two hinge-lines may be formed on the marker, one for one side of the door and one for the other.

It will be seen that the surface of the marker which is exposed when the marker is placed upon the door, as shown in Fig. l, is that surface which is hidden from view, and is placed against the door when the marker is reversed, as shown in Fig. 2. For this reason I prefer in all cases to so imprint the marks upon the body of the marker that they will bevisible upon both sides thereof; but it is not essential that the marker should be so formed at first, because the act of prieking in the marks when the marker is first applied to the door, as shown in Fig. l. will leave them visible upon the other surface of the wing B when the marker is reversed.

IVhile I prefer to form the several marks for cutting and boring by means of punctured or indented lines, and to transfer the same to the door by a piercing-instrument, said marks may be formed by means of a suitable ink, which can be transferred to the door by a slight pressure after the marker is properly placed upon the door. When a larger sheet, as shown in'Fig. 3, is used, the mortisc-marks h 7i may be formed upon the edge of the door by a k nife-point or other suitable puncturinginstrument forced through the paper upon the lines a a.

The markers illustrated in Figs. 4; and 5 are used in the same manner as hercinbefore described for using the marker illustrated in Figs. l, 2, and 3, but,inasmuch as the rimlock is screwed upon one side of the door, and as the secondary spindle-hole and key-hole of night-latchesand master-key locks, 83e., are made upon one side of the door only, the marks for the screw-holes c, and spindle and key holes f and g will be used for pricking said marks upon one side of the door only.

Vhile I prefer at all times, as a matter of great convenience, to employ the folding reversible wing A, it is evident that the marker might be made with rigid blades having two wings, A, in plan View like a T, and then be used in the manner hereinbeforc described. It is also evident that the blade A maybe wholly dispensed with, in which case the upper and lower edges of the blade B could be used as indices to lay off the distance between the marks h h for the mortise, and a try-square could be used for gaging the direction of said marks across the edge of the door. The blade B will then be placed upon the side of the door, brought to the proper height to match the marks 7L 71 while the dedge of the paper e 292.463 v s :a

which corresponds to the line b will be brought even with the edge of the door to square the position of the blade B, after which the cutting and boring marks can be pricked upon the door, as before described. The blade can then be placed in like manner upon the opposite side of the door for marking that side. It is because the blade B is double-faced and has a flat face upon each of its two opposite sides that I am enabled to thus reverse it for marking the opposite sides of the door.

I have herein shown my lock-marker as adapted for use in putting on three styles of locks; but it is believed that these are sufficient to illustrate the marker and the manner of using the same, as it is only necessary to change the character of the imprints to conform .to the Various cuttings and borings for the article to be applied.

In some styles of drawer-locks and other articles the cuttings and borings are ,principally'made upon one side only, and in that case it will not be necessary to place the marker upon the opposite side of the rail or stile into which the article-is to be fitted.

The several marks of the proper form for key-holes, spindle -holes, 85o., will of themselves indicate their uses; butin addition thereto suitable directions or explanations may accompany each marker, and it would be very convenient to have such matter printed upon the marker itself. The blade A is the best place to print such matter.

In addition to the marks or indices hereinbefore described, other features of the article for which the marker is intended may also be imprinted upon the marker, so as form substantially a picture of said article; but in all cases it is necessary that the working-marks shall be isometrical with the article for which the marker is designed.

By making these markers of paper. or other also, that guides for directing a hand-driven bit in boring holes for locks have been shown and described in a prior patent; and I hereby disclaim the same.

I claim as my invention- 1. The herein-described marker, consisting of a double-faced blade or sheet having suitable indices for laying out the borings and cut- ,tings to be made. in fitting articles to doors,

&c., said indices being definitely located with reference togaging from a'given working-edge, substantially' as described, and for the purpose specified.

2. The herein-described marker, consisting of the blade A, having suitable indices for laying out the two edges of the mortise at the edge of a stile, and the blade B, connected' to the blade A, and provided with suitable -indices for laying out upon the side of a stile the borings and cuttings to be made in fitting articles to doors, Src., substantially as described, and for the purpose specified.

3. The herein-described marker, consisting of the blades B and the folding blade A, attached thereto, said marker having suitable indices for laying out the borings and cuttings to be made in fitting articles ro doors, 8m., substantially as described, and for the purpose specified. u'
